Steidlmayer Law was established by Leo Steidlmayer in 1979.

Leo earned his undergraduate degree and played basketball at Santa Clara University (Class of 1967). He went on to attend law school at the University of California, Davis, and began his legal career as a deputy district attorney in Butte County before joining a private firm in Chico. In 1979, Leo returned to his hometown of Colusa to establish his own practice. After a long and distinguished career serving the community, he now holds the role “Of Counsel” at Steidlmayer Law, and is valued for his practical, solution-oriented advice.

Born and raised in Colusa, with a long family history in the area, Leo has remained deeply invested in the community. He is a former member of the Knights of Columbus and the Colusa Rotary Club. An avid tennis player, Leo has coaches players of all ages, shares his passion for the sport, and serves as a community advocate for the use and upkeep of Colusa’s public courts.

In 2013, Leo was joined in practice by his youngest son, Luke Steidlmayer. Luke’s wife, Erin, joined the firm in 2014.

Raised in Colusa as one of five children, Luke graduated from Colusa High School and earned his undergraduate degree in Economics from the University of California, Davis. Following his time at UC Davis, Luke spent five years playing minor league baseball in the San Diego Padres organization. After his baseball career concluded, he returned to school and earned his law degree from Santa Clara University.

Luke began his legal career as a civil litigator at a large firm based in Sacramento, focusing on general litigation with an emphasis on real property and commercial disputes. In 2013, he returned to Colusa to join his father at Steidlmayer Law, where he practiced for 11 years before being elected Judge of the Colusa County Superior Court.

Erin E. Steidlmayer was born in Honolulu, Oahu, and has lived in Northern California since childhood. She earned her undergraduate degree from the University of California, Davis, and her law degree from Santa Clara University School of Law. While in law school, she studied abroad at Oxford University through Santa Clara’s summer program and served as a technical editor for the Santa Clara High Technology Law Journal. After graduating, she worked as a senior license consultant at Oracle America, Inc. In 2014, Erin moved to Colusa to join her husband and father-in-law at Steidlmayer Law. Her transition to Colusa inspired her to focus her legal practice on estate planning, a field that closely reflects both her personal values and the needs of the local community. Erin is proud to be an active member of Colusa, volunteering in local classrooms, coaching youth soccer, and serving on the Colusa Unified School District Board of Trustees.
